sponding units. It contains the following keys:

Table 5-3: Keys on the keypad

Type of key Description

Alphanumeric keys Enter numbers and (special) characters in edit dialog boxes.

Decimal point Inserts a decimal point "." at the cursor position.

Sign key Changes the sign of a numeric parameter. In the case of an

alphanumeric parameter, inserts a "-" at the cursor position.

Unit keys

(G/n dBμV, M/μ μV, k/m mV

and x1 dB(m))

These keys add the selected unit to the entered numeric value

and complete the entry.

In the case of level entries (e.g. in dB) or dimensionless values,

all units have the value "1" as multiplying factor. Thus, they have

the same function as an [Enter] key.

5.1.6 Navigation Controls

The navigation controls include a rotary knob, navigation keys, and the display

keys. They allow you to navigate within the display or within dialog boxes.

5.1.6.1 Rotary Knob

The rotary knob has several functions:

●

Increments (clockwise direction) or decrements (counterclockwise direction)

the instrument parameter at a defined step width in the case of a numeric

entry.

●

Moves the selection, e.g. to a function block in the block diagram

●

Shifts the selection bar within focused areas (e.g. lists).

●

Acts like the [Enter] key, when it is pressed.

5.1.6.2 Editing Keys

Editing keys enable you to confirm an entry, delete individual characters, or exit

the current operation.
